2019 Mazda 6 — MOT failures & pass rate
The 2019 Mazda 6 passed 92.0% of its 19,529 recorded MOT tests. Large family cars of a similar age fail 11.5% of the time, so this is 3.5pp better than the group it competes with. Failures cluster in tyres, visibility and brakes.
What the MOT record shows
No single area dominates — tyres (3.4%) and visibility (2.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, brake pads and headlamp aim — wipers alone was recorded 488 times.
Mileage matters less than usual here: the 2019 6 fails 4.9% of the time in the 0-30k band and 8.6% at 150k+, a spread of only 3.7 points.
Fuel type barely separates them — petrol fails 7.5% of the time against 8.9% for diesel.
Advisories point at the next bill rather than this one: tyres was flagged on 21.2% of tests without failing them.
The trend is worsening — 4.7% of tests failed in 2021 against 10.0% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2019 6
On a 2019 6, tyres is what the MOT record says goes wrong most — it appeared in 3.4% of tests. Check these areas before you commit.
- Tyres (3.4% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Visibility (2.7% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Brakes (2.4% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
